I have installed hostapd as package for Ubuntu 12.04. Everything is configured and works great for about 10 minutes; after that, packets start to get dropped and eventually I can't even connect. Restarting the hostapd service seems to fix everything for a further 10 minutes.

I am fairly fresh to Linux. What steps I can take to further debug this behaviour?

Try disabling WMM in your config with wmm_enabled=0. There could be a powersave feature kicking in. I had a similar issue and this solved it for me.
